The molecule Al2(SO4)3 has dissolved in water. What ions are formed and how many ions are formed of each type?

5 ions will be formed

When the molecule Al2(SO4)3 dissolves in water, it dissociates into ions. Let's break down the molecule step by step:

1. The first thing to note is that Al2(SO4)3 is a compound containing aluminum (Al) and sulfate (SO4) ions.

2. Aluminum sulfate (Al2(SO4)3) dissociates into two aluminum ions (Al3+) and three sulfate ions (SO4^2-).

So, when Al2(SO4)3 dissolves in water, it forms a total of 2 aluminum ions (Al3+) and 3 sulfate ions (SO4^2-).

To determine the ions formed when the molecule Al2(SO4)3 dissolves in water, we need to understand the formula and the concept of ionic compounds.

In this case, Al2(SO4)3 is an ionic compound made up of aluminum (Al) and sulfate (SO4) ions. The subscript numbers indicate the number of each ion present in the formula.

First, let's break down the formula and identify the ions:

1. Aluminum Ion (Al3+): The subscript "2" in Al2 means that two aluminum ions are present.

2. Sulfate Ion (SO42-): The subscript "3" in (SO4)3 means that three sulfate ions are present.

When the Al2(SO4)3 molecule dissolves in water, it dissociates into its constituent ions. Each aluminum ion (Al3+) and each sulfate ion (SO42-) break apart and become hydrated in the water, surrounded by water molecules.

So, when Al2(SO4)3 dissolves in water, it forms:

- 2 aluminum ions (Al3+)
- 3 sulfate ions (SO42-)

Therefore, two aluminum ions (Al3+) and three sulfate ions (SO42-) are formed when Al2(SO4)3 dissolves in water.
